MOUNTINGAll P-Series Gauges and PC-Series Controllers have mounting holes for convenient mounting to flat panels. These gauges are position insensitive and can be mounted in any orientation. The sizes and dimensions for the mounting holes are shown on pages 49 to 64.P-Series Pressure Gauges may be connected into your system with the flow going in either direction for ease of viewing the display. These units are shipped with a plug for dead end applications. This plug should be removed for flow through applications.PC-Series Vacuum and Pressure Controllers are normally intended to control the process pressure downstream of the controller. In order for this to occur the controller should be mounted so the flow goes from left to right as you look at the front of the unit. This puts the measuring portion of the device between the valve and the leakage point where you are attempting to control the pressure application. Back-pressure controllers reverse this configuration (see page 30).

PLUMBINGYour instrument is shipped with plastic plugs fitted in the port openings. To lessen the chance of contaminating the flow stream do not remove these plugs until you are ready to install the device.Make sure that flow is in the direction indicated by the flow arrow.

Standard P-Series Gauges and PC-Series Controllers have female inlet and outlet port connections. Welded VCR and other specialty fittings may have male ports.The inlet and outlet port sizes (process connections) for different flow ranges are shown on pages 49-64.Instruments with M5 (10-32) ports have O-ring face seals and require no sealant or tape. Do not use tape with welded or O-ring fittings.For non M5 (10-32) ports use thread sealing Teflon® tape to prevent leakage around the port threads. Do not wrap the first two threads. This will minimize the possibility of getting tape into the flow stream and flow body.

Do not use pipe dopes or sealants on the process connections as these compounds can cause permanent damage to the controller should they get into the flow stream.

When changing fittings, carefully clean any tape or debris from the port threads.For additional notes on PCD (dual valve controller) plumbing see page 34.For gas applications, it is recommended that a 40 micron filter be installed upstream of P and PCR-Series instruments and a 20 micron filter be installed upstream of PC and PCD-Series instruments. For liquid applications, see “Using Pressure Instruments with Fluids”, page 8.

USING PRESSURE INSTRUMENTS WITH FLUIDS

All of these devices may by used with chemically compati ble liquids providing a couple of things are taken into account:

1. Water is about 50 ti mes more viscous than air. This is important when sizing a pressure controller. The PC-Series which can be used to fl ow up to 20 SLPM of gas, will be limited to roughly 0.5 LPM of water-like fl uid. The PCR will be limited to roughly 30 LPM of water-like fl uid.

2. The factory PID tune is established using air fl ow. It may be necessary to adjust the PID tuning parameters if you will be using a controller with liquids.

SPECIAL CONFIGURATIONS

P, PC, and PCR-Series pressure devices are occasionally ordered with special confi gurati ons which are covered here:

1. External Sense Port: Occasionally it is necessary or desirable to sense the pressure at some point other than at the locati on of the pressure device. All P, PC, or PCR-Series pressure devices can be ordered with an additi onal NPT port which is connected directly with the pressure sensor of the device. In these devices the fl ow path through the device is NOT connected to the pressure sensor. See “PC3-Series Pressure Controllers” – page 31.

2. Diff erenti al Pressure: Occasionally it is necessary or desirable to monitor or control a diff erenti al pressure. P, PC, and PCR-Series pressure devices can be ordered as low diff erenti al pressure devices (usually 1 to 5 psid). These devices have two ports located on the front face of the unit for connecti on to the points in the system where the diff erenti al pressure is to be measured. The upstream port is for the higher pressure and the downstream port is for the lower pressure. In these devices the fl ow path through the device is NOT connected to either leg of the diff erenti al pressure sensor. See “Diff erenti al Pressure Gauges and Diff erenti al Pressure Controllers” – page 33.

CAUTION! Eceeding the maimum speciied ine pressure ma cause permanent damage to the soid-state dierentia pressure transducer.

POWER AND SIGNAL CONNECTIONSPower can be supplied to your gauge/controller through either the power jack or the 8 pin Mini-DIN connector. An AC to DC adapter which converts line AC power to DC voltage and current as specified below is required to use the power jack. A 2.1mm, positive center, 7-30 Vdc AC/DC adapter rated for at least 100 mA is required to use the adapter jack in a P-Series meter.A 2.1mm, positive center, 12-30 Vdc AC/DC adapter rated for at least 250 mA is required to use the adapter jack in a PC-Series controller. A 2.1mm, positive center, 24-30 Vdc AC/DC adapter rated for at least 500 mA is required to use the adapter jack in a PCR-Series controller.NOTE: 4-20mA analog output requires at least 15 Vdc.

CAUTION! Do not connect power to pins 1 through 6 as permanent damage can occur!

It is common to mistake Pin 2 (labeled 5.12 Vdc Output) as the standard 0-5 Vdc analog output signal. In fact Pin 2 is normally a constant 5.12 Vdc that reflects the system bus voltage and can be used as a source for the set-point signal.For 6 Pin Locking Connector Pin-outs see page 66.

OUTPUT SIGNALS

RS-232 Digital Output Signal

To use the RS-232 output signal, it is necessary to connect the RS-232 Output Signal (Pin 5), the RS-232 Input Signal (Pin 3), and Ground (Pin 8) to your computer serial port as shown on page 8. (See page 35 for details on accessing RS-232 output.)

Standard Voltage (0-5 Vdc) Output Signal

Gauges/controllers equipped with a 0-5 Vdc (opti onal 0-10 Vdc) will have this output signal available on Pin 6. This output is generally available in additi on to other opti onally ordered outputs. This voltage is usually in the range of 0.010 Vdc for zero fl ow and 5.0 Vdc for full-scale fl ow. The output voltage is linear over the enti re range. Ground for this signal is common on Pin 8.

Opti onal 0-10 Vdc Output Signal

If your gauge/controller was ordered with a 0-10 Vdc output signal, it will be available on Pin 6. (See the Calibrati on Data Sheet that shipped with your device to determine which output signals were ordered.) This voltage is usually in the range of 0.010 Vdc for zero fl ow and 10.0 Vdc for full-scale fl ow. The output voltage is linear over the enti re range. Ground for this signal is common on Pin 8.

Opti onal Current (4-20 mA) Output Signal

If your gauge/controller was ordered with a 4-20 mA current output signal, it will be available on Pin 1. (See the Calibrati on Data Sheet that shipped with your device to determine which output signals were ordered.) The current signal is 4 mA at 0 fl ow and 20 mA at the device’s full scale fl ow. The output current is linear over the enti re range. Ground for this signal is common on Pin 8. (Current output units require 15-30Vdc power.)

Opti onal 2nd Analog Output Signal

You may specify an opti onal 2nd analog output on Pin 2 at ti me of order. (See the Calibrati on Data Sheet that shipped with your device to determine which output signals were ordered.) This output may be a 0-5 Vdc, 0-10 Vdc, or 4-20 mA analog signal that can represent any measured parameter. With this opti onal output, a meter could output the volume fl ow rate (0-5 Vdc on pin 6) and the line temperature (0-5 Vdc on pin 2).

If your device is CSA/ATEX approved or equipped with the opti onal six pin industrial connector, please contact Cole-Parmer.

MAIN This mode defaults on power up, with fl ow as the primary displayed parameter. The following parameters are displayed in the Main mode.Line Pressure shows the pressure in the units specifi ed at ti me of order.

Tare: Pushing the TARE P butt on tares the pressure gauge and provides it with a reference point for zero pressure.

This is an important step in obtaining accurate measurements. It is best to zero the pressure gauge each ti me it is

powered up. If the pressure reading varies signifi cantly from zero aft er an initi al tare, give the unit a minute or so to warm up and re-zero it.

If in doubt about whether the pressure is zero, remove the gauge from the line and open both ports to atmosphere before entering the Tare command. For liquid pressure devices, all liquid must be drained from the gauge and any plumbing between the gauge and the atmosphere.

If the unit reads signifi cantly diff erent than zero when it is exposed to atmospheric pressure, it is a good indicati on that it was given a false tare.

MISCELLANEOUS Miscellaneous is accessed by pressing the MISC button on the Select Menu display. Next select either MISC1 or MISC2.

MISC1 will display as shown at left.ZERO BAND refers to Display Zero Deadband. Zero deadband is a value below which the display jumps to zero. This deadband is often desired to prevent electrical noise from showing up on the display as minor flows or pressures that do not exist. Display Zero Deadband does not affect the analog or digital signal outputs.ZERO BAND can be adjusted between 0 and 3.2% of the sensor’s Full Scale (FS). Press ZERO BAND. Then use SELECT to choose the digit with the arrow and the UP and DOWN buttons to change the value. Press SET to record your value. Press CLEAR to return to zero.Pressure Averaging and Flow Averaging may be useful to make it easier to read and interpret rapidly fluctuating pressures and flows. Pressure and flow averaging can be adjusted between 1 (no averaging) and 256 (maximum averaging). These are geometric running averages where the number between 1 and 256 can be considered roughly equivalent to the response time constant in milliseconds.

CONTROL SETUP (conti nued)LOOP VAR—Pressure controllers are defaulted to pressure. Pressure means that the controller is “closing the loop” on the pressure. This means that when you give the controller a set-point, the controller compares that set-point to the measured pressure and adjusts the valve to try to make the pressure and the set-point match. For the pressure, the input signal (e.g. 0-5 Vdc) corresponds to the full-scale pressure for the device.

CONTROL SETUP (conti nued)

Tareing (or zeroing) a gauge pressure or diff erenti al pressure controller provides it with a reference point for zero pressure.

OFF AUTO / ON AUTO—this feature allows you to tare the controller.

The controller must be left in the default OFF AUTO mode except when actually tareing the controller as explained below.

It is, however, very important to perform this adjustment only when you are certain that the process ports are open to atmosphere and that there is No Flow!

For liquid pressure devices, all liquid must be drained from the system. To correctly tare a gauge pressure or diff erenti al pressure controller:

1. Be sure the unit is in the OFF AUTO default setti ng.2. Disconnect all plumbing and make sure there is No Flow.3. Push the butt on below OFF AUTO once so that the display reads ON AUTO.4. Enter a Set-Point of ZERO. A zero set-point results in the closing of the valve and a known “no fl ow” conditi on.5. Wait at least 30 seconds.6. Push the butt on below ON AUTO once so that the display reads OFF AUTO.7. Reconnect the plumbing.

If the unit reads signifi cantly diff erent than zero, when removed from the line and open, it is a good indicati on that it was given a false zero.

If your pressure controller was ordered with the opti onal “Tare-P”, you may tare it following the instructi ons for tareing a pressure gauge on page 16

PID TUNING

PID Values determine the performance and operation of your proportional control valve. These terms dictate control speed, control stability, overshoot and oscillation. All units leave the factory with a generic tuning designed to handle most applications. If you encounter issues with valve stability, oscillation or speed, fine tuning these parameters may resolve the problem.PC-Series controllers allow you to adjust the Proportional, Integral and Differential terms of the PID control loop. To change the PID loop parameters, push the button below PID.Press LOOP TYPE. Then use the LN-UP and LN-DN buttons to select the appropriate PID control algorithm. Press SET.See the following page for descriptions of the PID Loop Types (PID Control Algorithms).

P refers to the Proportional term of the PID loop. I refers to the Integral term of the PID loop. D refers to the Differential term of the PID loop. Press P, I or D. Then use SELECT to choose the decimal with the arrow and the UP and DOWN buttons to change the value. Press SET to record your value. Press CLEAR to return to zero.

Before changing the P, I or D parameter, please record the initial value so that it can be returned to

the factory setting if necessary.Valve tuning can be complex. If you would like assistance, please contact Cole-Parmer for technical support.

The PD algorithm is the PID algorithm used on most pressure controllers.It is divided into two segments:The first compares the process value to the set-point to generate a proportional error. The proportional error is multiplied by the ‘P’ gain, with the result added to the output drive register. The second operates on the present process value minus the process value during the immediately previous evaluation cycle. This ‘velocity’ term in multiplied by the ‘D’ gain, with the result subtracted from the output drive register. The above additions to and subtractions from the output drive register are carried over from process cycle to process cycle, thus performing the integration function automatically. Increasing the ‘P’ gain will promote the tendency of the system to overshoot, ring, or oscillate. Increasing the ‘D’ gain will reduce the tendency of the system to overshoot. The PD2I algorithm is a PID algorithm used primarily for high performance pressure and flow control applications. It exhibits two basic differences from the PD algorithm that most controllers utilize.

1. Instead of applying a damping function based upon the rate of change of the process value, it applies a damping function based upon the square of the rate of change of the process value.2. The damping function is applied directly to the proportional error term before that term is used in the proportional and integral functions of the algorithm. This provides a certain amount of ‘look ahead’ capability in the control loop.

Because of these differences, you will note the following:1. Increasing ‘P’ gain can be used to damp out overshoot and slow oscillations in pressure controllers. You will know that ‘P’ gain is too high, when the controller breaks into fast oscillations on step changes in set-point. On flow controllers, too high a ‘P’ gain results in slower response times. Too low a ‘P’ gain results in overshoot and/or slow oscillation. A good starting value for ‘P’ gain is 200.2. If the unit was originally shipped with the PD2I algorithm selected, the ‘D’ gain value should be left at or near the factory setting because it relates primarily to the system phase lags. If you are changing from the default algorithm to the PD2I algorithm, you should start with a ‘D’ gain value of 20.3. The ‘I’ gain is used to control the rate at which the process converges to the set-point, after the initial step change. Too low a value for ‘I’ gain shows up as a process value that jumps to near the set-point and then takes awhile to converge the rest of the way. Too high a value for ‘I’ gain results in oscillation. A good starting value for the ‘I’ gain is 200.

PC3 AND PCR3 SERIES PRESSURE CONTROLLERS:

The PC3 (and PCR3) pressure controller is designed to change the flow to allow the control of pressure at some point away from the body of the controller.

This is most helpful when it is necessary to mount pneumatic components such as valves, fittings or flow meters that introduce significant pressure drop between pressure controller body and the point where pressure control is necessary.

To accomplish this, the PC3 has an external sensing port to which the pressure at the location where pressure is to be controlled is piped back to the pressure sensor in the controller.

DIFFERENTIAL PRESSURE GAUGES:

The differential pressure gauge is designed to measure a pressure difference between two points in the line. There are a variety of applications for this device.

One of the most common is to measure the difference in pressure across some sort of element that changes resistance to flow over time, such as a filter, or one that changes area with time as would happen with orifice testing.

The gauge has two sensing ports which are piped to the upstream and downstream sides of the pressure drop of interest in the system.

These two ports run either to two separate pressure sensors or for low differential pressures – they may be run to the two legs of a single differential pressure sensor. The higher (upstream) pressure is applied to the left port and the lower (downstream) pressure is applied to the right port.

PCD-SERIES DUAL VALVE PRESSURE CONTROLLER OPERATIONPCD-Series Closed Volume Pressure Controllers incorporate a digital pressure gauge with dual control valves and circuitry. The integrated PID loop measures the pressure, compares it with the set-point, and adjusts either the Inlet or Exhaust valve accordingly in excess of two thousand times per second. It is most common to have a .050 inch diameter orifice in the inlet valve, and a .050 inch diameter exhaust valve. The response time of the system will depend on the size of the volume being controlled and the feed pressure. The controllers are intended for use with clean, non-corrosive gases only. They are designed with a feed port, a process port, and an exhaust port. This allows the controllers to raise and lower the pressure of a closed system within the operating range of the controller without wasting gas under constant pressure conditions.PlumbingConnect your PCD into your process via the 1/8” NPT port on the front of the unit. This is the “Process” port. Connect a supply pressure greater than the full scale pressure control range of the device, not to exceed 145 psig, to the inlet 1/8” NPT port on the left side device. This is the “Inlet” port. The 1/8” NPT “Exhaust” port, located on the right side of the device can vent to atmosphere if the application is suitable, or to a collection network if necessary. The pressure at the exhaust port should be at atmospheric pressure or below to allow the controller to be used over its full scale range. If desired, there are two 8-32 mounting holes located on the bottom of the unit as shown in the dimensional drawing on page 53. Connect your PCD to power and output lines as detailed on pages 9 - 12.

RS-232 OUTPUT AND INPUTConfiguring HyperTerminal®:1. Open your HyperTerminal® RS-232 terminal program (installed under the

“Accessories” menu on all Microsoft Windows® operating systems).2. Select “Properties” from the file menu.3. Click on the “Configure” button under the “Connect To” tab. Be sure the

program is set for: 19,200 baud (or matches the baud rate selected in the RS-232 communications menu on the meter) and an 8-N-1-None (8 Data Bits, No Parity, 1 Stop Bit, and no Flow Control) protocol.

4. Under the “Settings” tab, make sure the Terminal Emulation is set to ANSI or Auto Detect.

5. Click on the “ASCII Setup” button and be sure the “Send Line Ends with Line Feeds” box is not checked and the “Echo Typed Characters Locally” box and the “Append Line Feeds to Incoming Lines” boxes are checked. Those settings not mentioned here are normally okay in the default position.

6. Save the settings, close HyperTerminal® and reopen it.Streaming ModeIn the default Polling Mode, the screen should be blank except the blinking cursor. In order to get the data streaming to the screen, hit the “Enter” key several times to clear any extraneous information. Type “*@=@” followed by “Enter” (or using the RS-232 communication select menu, select @ as identifier and exit the screen). If data still does not appear, check all the connections and COM port assignments.Streaming Mode – Advanced The streaming data rate is controlled by register 91. The recommended default rate of data provision is once every 50 milliseconds and this is suitable for most purposes. If a slower or faster streaming data rate is desired, register 91 can be changed to a value from 1 millisecond to 65535 milliseconds, or slightly over once every minute. Below approximately 40 milliseconds, data provision will be dependent upon how many parameters are selected. Fewer data parameters can be streamed more quickly than more. It is left to the user to balance streaming speed with number of parameters streamed. To read register 91, type “*r91” followed by “Enter”. To modify register 91, type “*w91=X”, where X is a positive integer from 1 to 65535, followed by “Enter”. To return to the recommended factory default streaming speed, type “*w91= 50”.

36

Tareing via RS-232 (Gauges only):Tareing (or zeroing) the pressure gauge provides it with a reference point for zero pressure. This is a very simple but important step in obtaining accurate measurements. It is good practice to “zero” the pressure gauge each time it is powered up. If the pressure reading varies significantly from zero after an initial tare, give the unit a minute or so to warm up and re-zero it. Zeroing the unit while there is any pressure will directly affect the accuracy by providing a false zero point. If in doubt about whether the pressure is zero, remove it from the line and open both ports to atmosphere before entering the Tare command. If the unit reads a significant negative value when removed from the line and open, it is a good indication that it was given a false zero. To send a Tare command via RS-232, enter the following strings:In Polling Mode: Address$$P<Enter> (e.g. B$$P<Enter>)Sending a Set-point via RS-232 (Controllers only): To send a set-point via RS-232, “Serial” must be selected under the “Input” list in the control set up mode. Method 1: Set-point may be set in floating point in serial communication using serial command (UnitID)SX.YZ

Example: AS4.54 results in Unit ID A changing set-point to 4.54. Method 2: Type in a number between 0 and 65535 (2% over range), where 64000 denotes full-scale flow rate, and hit “Enter”. The set-point column and pressure rates should change accordingly. If they do not, try hitting “Enter” a couple of times and repeating your command. The formula for performing a linear interpolation is as follows: Value = (Desired Set-point X 64000) / Full Scale Pressure RangeFor example, if your device is a 50 psig full-scale unit and you wish to apply a set-point of 12.5 psig you would enter the following value: 16000 = (12.5 psig X 64000) / Full Scale Pressure RangeIf the controller is in polling mode as described in Changing from Streaming Mode to Polling Mode, the set-point must be preceded by the address of the controller. For example, if your controller has been given an address of D, the set-point above would be sent by typing: D16000 followed by “Enter”

37

To adjust the Proportional and Differential (P&D) terms via RS-232 (PC and PCR-Series only):Type *@=A followed by “Enter” to stop the streaming mode of information.To adjust the “P” or proportional term of the PID controller, type *R21 followed by “Enter”.The computer will respond by reading the current value for register 21 between 0-65535. It is good practice to write this value down so you can return to the factory settings if necessary. Enter the value you wish to try by writing the new value to register 21. For example, if you wished to try a “P” term of 220, you would type *W21=220 followed by “Enter” where the bold number denotes the new value.The computer will respond to the new value by confirming that 21=220. To see the effect of the change you may now poll the unit by typing A followed by “Enter”. This does an instantaneous poll and returns the values once. You may type A “Enter” as many times as you like. Alternately, you could resume streaming mode by typing *@=@ followed by “Enter”. Repeat step 3 to remove the unit from the streaming mode.To adjust the “D” or proportional term of the PID controller, type *R22 followed by “Enter”.The computer will respond by reading the current value for register 22 between 0-65535. It is good practice to write this value down so you can return to the factory settings if necessary. Enter the value you wish to try by writing the new value to register 22. For example, if you wished to try a “D” term of 25, you would type *W22=25 followed by “Enter” where the bold number denotes the new value. The computer will respond to the new value by confirming that 22=25. To see the effect of the change you may now poll the unit by typing A followed by “Enter”. This does an instantaneous poll and returns the values once. You may type A “Enter” as many times as you like. Alternately you could resume streaming mode by typing *@=@ followed by “Enter”. Repeat. You may test your settings for a step change by changing the set-point. To do this type A32000 (A is the default single unit address, if you have multiple addressed units on your RS-232 line the letter preceding the value would change accordingly.) followed by “Enter” to give the unit a ½ full scale set-point. Monitor the unit’s response to the step change to ensure it is satisfactory for your needs. Recall that the “P” term controls how quickly the unit goes from one set-point to the next, and the “D” term controls how quickly the signal begins to “decelerate” as it approaches the new set-point (controls the overshoot).

38

Changing From Streaming to Polling Mode:

When the meter is in the Streaming Mode the screen is updated approximately 10-60 times per second (depending on the amount of data on each line) so that the user sees the data essentially in real time. It is sometimes desirable, and necessary when using more than one unit on a single RS-232 line, to be able to poll the unit.

In Polling Mode the unit measures the flow normally, but only sends a line of data when it is “polled”. Each unit can be given its own unique identifier or address. Unless otherwise specified each unit is shipped with a default address of capital A. Other valid addresses are B thru Z.

Once you have established communication with the unit and have a stream of information filling your screen:

1. Type *@=A followed by “Enter” (or using the RS-232 communication select menu, select A as identifier and exit the screen) to stop the streaming mode of information. Note that the flow of information will not stop while you are typing and you will not be able to read what you have typed. Also, the unit does not accept a backspace or delete in the line so it must be typed correctly. If in doubt, simply hit enter and start again. If the unit does not get exactly what it is expecting, it will ignore it. If the line has been typed correctly, the data will stop.

2. You may now poll the unit by typing A followed by “Enter”. This does an instantaneous poll of unit A and returns the values once. You may type A “Enter” as many times as you like. Alternately you could resume streaming mode by typing *@=@ followed by “Enter”. Repeat step 1 to remove the unit from the streaming mode.

3. To assign the unit a new address, type *@=New Address, e.g. *@=B. Care should be taken not to assign an address to a unit if more than one unit is on the RS-232 line as all of the addresses will be reassigned. Instead, each should be individually attached to the RS-232 line, given an address, and taken off. After each unit has been given a unique address, they can all be put back on the same line and polled individually.

39

Collecting Data:

The RS-232 output updates to the screen many times per second. Very short-term events can be captured simply by disconnecting (there are two telephone symbol icons at the top of the HyperTerminal® screen for disconnecting and connecting) immediately after the event in question. The scroll bar can be driven up to the event and all of the data associated with the event can be selected, copied, and pasted into Microsoft® Excel® or other spreadsheet program as described below.

For longer term data, it is useful to capture the data in a text file. With the desired data streaming to the screen, select “Capture Text” from the Transfer Menu. Type in the path and file name you wish to use. Push the start button. When the data collection period is complete, simply select “Capture Text” from the Transfer Menu and select “Stop” from the sub-menu that appears.

Data that is selected and copied, either directly from HyperTerminal® or from a text file can be pasted directly into Excel®. When the data is pasted it will all be in the selected column. Select “Text to Columns...” under the Data menu in Excel® and a Text to Columns Wizard (dialog box) will appear. Make sure that “Fixed Width” is selected under Original Data Type in the first dialog box and click “Next”. In the second dialog box, set the column widths as desired, but the default is usually acceptable. Click on “Next” again. In the third dialog box, make sure the column data format is set to “General”, and click “Finish”. This separates the data into columns for manipulation and removes symbols such as the plus signs from the numbers. Once the data is in this format, it can be graphed or manipulated as desired.

For extended term data capture see: “Sending a Simple Script to HyperTerminal®” on page 41.

Data Format:

The data stream on the screen represents the pressure parameters of the main mode in the units shown on the display. For P-Series Pressure Gauges, there is a single column of data. This column represents the measured pressure in the units specified at time of order and shown on the display.

Sending a Simple Script File to HyperTerminal®

It is sometimes desirable to capture data for an extended period of time. Standard streaming mode information is useful for short term events, however, when capturing data for an extended period of time, the amount of data and thus the file size can become too large very quickly. Without any special programming skills, you can use HyperTerminal® and a text editing program such as Microsoft® Word® to capture text at defined intervals.

1. Open your text editing program, MS Word for example.

2. Set the cap lock on so that you are typing in capital letters.

3. Beginning at the top of the page, type A<Enter> repeatedly. If you’re using MS Word, you can tell how many lines you have by the line count at the bottom of the screen. The number of lines will correspond to the total number of times the flow device will be polled, and thus the total number of lines of data it will produce.For example: A

A A A A Awill get a total of six lines of data from the flow meter, but you can enter as many as you like.

The time between each line will be set in HyperTerminal.4. When you have as many lines as you wish, go to the File menu and select save. In the save dialog box, enter a path and file name as desired and in the “Save as Type” box, select the plain text (.txt) option. It is important that it be saved as a generic text file for HyperTerminal to work with it.

5. Click Save.

6. A file conversion box will appear. In the “End Lines With” drop down box, select CR Only. Everything else can be left as default.

7. Click O.K.

8. You have now created a “script” file to send to HyperTerminal. Close the file and exit the text editing program.

9. Open HyperTerminal and establish communication with your flow device as outlined in the manual.

10. Set the flow device to Polling Mode as described in the manual. Each time you type A<Enter>, the meter should return one line of data to the screen.

11. Go to the File menu in HyperTerminal and select “Properties”.

12. Select the “Settings” tab.

42

13. Click on the “ASCII Setup” button.

14. The “Line Delay” box is defaulted to 0 milliseconds. This is where you will tell the program how often to read a line from the script file you’ve created. 1000 milliseconds is one second, so if you want a line of data every 30 seconds, you would enter 30000 into the box. If you want a line every 5 minutes, you would enter 300000 into the box.

15. When you have entered the value you want, click on OK and OK in the Properties dialog box.

16. Go the Transfer menu and select “Send Text File…” (NOT Send File…).

17. Browse and select the text “script” file you created.

18. Click Open.

19. The program will begin “executing” your script file, reading one line at a time with the line delay you specified and the flow device will respond by sending one line of data for each poll it receives, when it receives it.You can also capture the data to another file as described in the manual under “Collecting Data”. You will be simultaneously sending it a script file and capturing the output to a separate file for analysis.

TROUBLESHOOTINGDisplay does not come on or is weak.Check power and ground connections and supply voltage. Please reference the technical specifications (pages 49-63) to assure you have the proper power for your model.

Pressure reading is approximately fixed either near zero or near full scale regardless of actual line pressure.Differential pressure sensor may be damaged. A common cause of this problem is instantaneous application of high-pressure gas as from a snap acting solenoid valve upstream of the meter. If you suspect that your pressure sensor is damaged please discontinue use of the controller and contact Cole-Parmer.

Displayed pressure is flashing and message POV is displayed:Our pressure gauges and controllers display an error message (POV = pressure overrange) when a the pressure exceeds the range of the sensors in the device. When any item flashes on the display, the pressure measurement is not accurate. Reducing the pressure to within specified limits will return the unit to normal operation and accuracy. If the unit does not return to normal contact Cole-Parmer.

My controller does not respond to the set-point.Check that your set-point signal is present and supplied to the correct pin and that the correct set-point source is selected under the SETPT SOURCE list in the control set up display (page 25). Also check that the unit is properly grounded.

After installation, there is no pressure.PC-Series Controllers incorporate normally closed valves and require a set-point to operate. Check that your set-point signal is present and supplied to the correct pin and that the correct input is selected under the SETPT SOURCE list in the control set up display (page 25). Also check that the unit is properly grounded.

The pressure lags below the set-point.Be sure there is enough pressure available. If either the set-point signal line and/or the output signal line is relatively long, it may be necessary to provide heavier wires (especially ground wiring) to negate voltage drops due to line wire length. An inappropriate PID tuning can also cause this symptom if the D term is too large relative to the P term. See pages 28 and 29 for more information on PID tuning.

Controller is slow to react to a set-point change or imparts an oscillation to the flow.An inappropriate PID tuning can cause these symptoms. Use at conditions considerably different than those at which the device was originally set up can necessitate a re-tuning of the PID loop. See pages 28 and 29 for more information on PID tuning. Note: The larger the volume pressured, the longer it takes to change the pressure in that volume.

44

The output signal is lower than the reading at the display.This can occur if the output signal is measured some distance from the gauge/controller as voltage drops in the wires increase with distance. Using heavier gauge wires, especially in the ground wire, can reduce this effect.

My controller oscillates wildly and/or exhibits very different reactions to the set-point than I expect.Conditions considerably different than those at which the device was originally set up can necessitate a re-tuning of the PID loop. See pages 28 and 29 for more information on PID tuning.

RS-232 Serial Communications is not responding.Check that your gauge is powered and connected properly. Be sure that the port on the computer to which the gauge is connected is active. Confirm that the port settings are correct per the RS-232 instructions in this manual (Check the RS-232 communications select screen for current gauge readings). Close HyperTerminal® and reopen it. Reboot your PC. See pages 11, 12 and 34 for more information on RS-232 signals and communications.

Slower response than specified.P-Series Gauges and PC-Series Controllers feature an RS-232 programmable Geometric Running Average (GRA). Depending on the full scale range of the gauge, it may have the GRA set to enhance the stability/readability of the display, which would result in slower perceived response time. Please see “Pressure Averaging” on page 19.

Jumps to zero at low pressure.P-Series Gauges and PC-Series Controllers feature an RS-232 programmable zero deadband. The factory setting is usually 0.5% of full scale. This can be adjusted between NONE and 3.2% of full scale. See page 19.

MAINTENANCE AND RECALIBRATIONGeneral: P, PC, PCR and PCD-Series Pressure Gauges and Controllers require minimal maintenance. They have no moving parts. The single most important thing that affects the life and accuracy of these devices is the quality of the gas being measured. The instruments are designed to measure CLEAN, DRY, NON-CORROSIVE gases. If your application requires an aggressive or corrosive gas, please consider PS, PCS, PCRS and PCDS-Series instruments (see page 61).Recalibration: The recommended period for recalibration is once every year. A label located on the back of the controller lists the most recent calibration date. The controller should be returned to the factory for recalibration within one year from the listed date. Before calling to schedule a recalibration, please note the serial number on the back of the meter. The Serial Number, Model Number, and Date of Manufacture are also available on the Model Info display (page 21).Cleaning: P, PC, PCR and PCD-Series Pressure Gauges and Controllers require no periodic cleaning. If necessary, the outside of the controller can be cleaned with a soft dry cloth. Avoid excess moisture or solvents.For repairs, recalibrations, or recycling of this product, contact:

The Li-Ion cell must not be removed.Normal batt ery life of a fully-charged cell is 18 hours with a monochrome display or 5 hours with a TFT color display, when the backlight is set to 10. Dimming the backlight will increase batt ery life.The batt ery can be charged through either the micro-USB port or the mini-DIN connector. When the device is connected to external power it will functi on normally while the batt ery is charging. Note: If the batt ery has no charge, a charge ti me of one minute will be required before the unit can be turned on. Charge rates will be fastest through the micro-USB port using the included power supply or equivalent. The device will charge fastest when it is turned off . Recharge Time: 3.5 hours with 2A USB supply. The micro-USB port is for charging purposes only.The green/red indicator LED on top of the device will light up green to indicate that the unit is charging. The green LED will turn off when the batt ery is charged and the power switch is turned to “I” for ON. The indicator LED fl ashes red when the device has about 1 hour of batt ery life remaining. The LED will fl ash red at a faster rate when the device has about 15 minutes of batt ery life remaining. It is highly recommended that the device be charged immediately. When the batt ery charge runs out, the display contrast will turn to 0 and device performance is no longer guaranteed.

Output signals from the meter are passed through the mini-DIN connector on top of the device. Rechargeable batt ery units do not support 0-10V analog output. Receiver resistance must be below 250Ω.

Turn the power switch on top of the device to “O” for OFF when it is not in use.Warning: If the device is left ON unti l the batt ery can no longer power it, the charge indicator will fall out of sync with the actual charge. The device can be re-synced by fully charging the batt ery once.

A Batt ery Charge Indicator appears below Tare on the display:

CAUTION! Do not operate or store the deice outside o the -10° to +50°C temperature range. I interna sensors detect that the temperature is outside o this range, the dispa contrast wi turn to 0 and the meter’s perormance is no onger guaranteed.

The sae charging temperature range is 0° to +45°C. I interna sensors detect temperatures outside o this range, the atter wi not charge.

Accessory: Multi -Drop Box

The Multi -Drop Box makes it convenient to wire multi ple fl ow and/or pressure devices to a single RS-232 port. Now available with a USB interface!

The Multi -Drop Box has nine 8 pin mini-DIN ports available. The ports are to be used with a standard double ended 8 pin mini-DIN (DC-62) style cable going from the box to each fl ow or pressure device.

A single DB9 D-SUB type connector (COM PORT) connects, using the included cable, to the serial connector on a PC or laptop.

All of the fl ow and/or pressure devices are powered via a terminal block on the front of the box.

If more than nine devices will be required, additi onal Multi -Drop Boxes can be daisy chained together with a double ended 8 pin mini-DIN cable plugged into any receptacle on both boxes.

Multi -Drop Box Power Supply for Large Valve Controllers: The PS24VHC (Power Supply 24Vdc High Current) is a 6.5Amp 24Vdc power supply designed for running multi ple large controllers on a Multi -Drop Box.

The 6.5Amp power supply can run as many as 8 large valve controllers, which makes it ideal for the Multi -Drop Box and multi ple large valve (or small valve / large valve combinati on) controllers on a Multi -Drop Box.
